CAIDA Near-Real-Time UCSD Network Telescope Traffic

Hourly compressed pcap files of raw IPv4 packets of unsolicited traffic captured by the UCSD Network Telescope instrumentation. The dataset contains near-real-time raw traces from the UCSD Network Telescope covering a 60-day sliding time window up to the present time. Once data slides out of the "near-real-time window", the pcap files are off-loaded to tape storage. These data provide opportunities to study network security-related events (DDoS attacks, worms, etc.) The size of one hourly raw data pcap file is more than 75Gb.
